Title: Method for erasing information of optical information recording and reproducing device
Inventor: TSUKADA MASAHARU
IPC: G11B7/30
Filed: 1985-04-16
Abstract: PURPOSE:To shorten the processing time of an optical information recording/ reproducing device by performing simultaneously both reproduction and erasion of information. CONSTITUTION:A pregroup of projected and recessed parts 5 and 7 is formed to a recording medium 1, and both parts 5 and 7 adjacent to each other form a track 9. The parts 5 and 7 are referred to as tracks C and D respectively. When the switches of switch circuits 35 and 73 are set as shown by solid lines respectively by the switch signal CO, a laser driver 31 supplies a signal to a semiconductor laser 13 for execution of a reproducing job and drives the laser 13. Thus the track C of the medium 1 is reproduced by a light beam A given from the laser 13. While the erasion signal is supplied to a laser driver 33 from a control part 45. Then a semiconductor laser 15 emits a light beam B of a fixed level of power, and the magnetic fields of the track D of the medium 1 are arranged in a fixed direction along the direction of a bias magnetic field. Then the track D is erased.

Title: Parallel flat plate type plasma etching device
Inventor: TSUBOUCHI NATSUO
IPC: H01L21/3065
Filed: 1979-06-20
Abstract: PURPOSE:To accurately etch a semiconductor wafer by altering the installing  method of the wafer between parallel flat plate electrodes to prevent the direct indicent charged particles to the wafer and to prevent the temperature from rising. CONSTITUTION:After the reaction gas of a chamber 4 becomes predetermined partial pressure, a high frequency voltage is applied to the electrode 1 to produce a plasma. The surface of a semiconductor wafer 3 is supported at 8 toward the electrode 2, and a shielding plate 9 is supporetd at 10 between the electrode 1 and  the wafer 3. In this manner, the surface of the wafer is not exposed with the high  energy charged particles to eliminate the temperature rise on the surface. Accordingly, the resist etching speed is retained low to etch the wafer 3 only on the free  substrate. Since the wafer is further directed downwardly, no residue of resist and  reaction product is adhered and accmumulated on the surface of the wafer so as to  finely form the wafer without defect. Even if the wafer 3 is vertically supported,  similar effect can be obtained.

Title: Image reader
Inventor: TAZAWA AKIRA
IPC: H04N1/04
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To output an image signal of high image quality by obtaining a focal position with the small influence of axial chromatic aberration by determining a final focal position on the basis of a specified color focal position obtained by a specified color focal position detecting means. SOLUTION: Color separation is performed by illuminating a film original in various colors (R, G, B and IR). It is necessary to determine a position showing the values for best balance in the ratio of respective MTF values of the colors R, G, B and IR as the focal position. In an example shown in figure, the ratio of respective MTF values of respective colors keeps a certain degree of balance at a position X and the position X1 is determined as the focal position. Therefore, when finding the focal position by performing auto-focusing in the color G with a film scanner, auto-focusing in the color G is executed, the G color focal position Gaf is determined, and next the position X1 deviated from a G color focal position Gaf by just for the difference (axial chromatic aberration) between the G color focal position Gaf, and the position X1 is determined as the focal position.
